AI agents for business finance: what they can and can't do
What AI agents can do in bookkeeping, close, collections and compliance today, where a person must stay in charge, and how to judge a product.
The short answer
A US citizen or resident who owns 10% or more of a Nigerian company, controls more than 50% of it, or is an officer or director when a US person acquires 10%, can have to file Form 5471 with their own tax return. The penalty for not filing is $10,000 per company per year, plus $10,000 for each 30 days after an IRS notice, up to $50,000 more, and a 10% cut in foreign tax credits (Form 5471 instructions, December 2025).
Who is a US person here
Form 5471 is about US persons with interests in foreign corporations. For a Nigerian in the US, that usually means US citizens (including dual citizens) and residents for tax, such as green card holders and many visa holders who meet the substantial presence test. A Nigerian private limited company is a foreign corporation for US purposes. Nigeria has no income tax treaty with the US (IRS treaty list, January 2026), so no treaty changes this.
The five filer categories
| Category | Who (Form 5471 instructions, Dec 2025) | Typical diaspora case |
|---|---|---|
| 1 | US shareholder of a section 965 specified foreign corporation | Rare for small family companies |
| 2 | US citizen or resident who is an officer or director of a foreign corporation in which a US person acquired 10%, or an additional 10% | You sit on the board of your family company in Lagos when your US-based brother buys 10% |
| 3 | US person who acquires stock reaching 10%, becomes a US person while holding 10%, or disposes of stock to fall below 10% | You get a green card while owning 30% of a Nigerian company |
| 4 | US person who controlled the corporation: more than 50% of votes or value | You own 60% of your Lagos company |
| 5 | US shareholder (10% or more) of a controlled foreign corporation on the last day it was a CFC | You and your US-citizen sister own 30% each |
One person can fall into several categories at once, and each company needs its own form.
When it is due
Form 5471 is attached to your income tax return (or partnership or exempt organisation return) and is due with it, including extensions. There is no separate filing address. If you extend your Form 1040, the 5471 is extended too.
What happens if you miss it
| Failure | Penalty (section 6038) |
|---|---|
| Not filing on time | $10,000 for each annual accounting period of each foreign corporation |
| Still not filed 90 days after an IRS notice | A further $10,000 for each 30-day period or part, up to $50,000 |
| Foreign tax credit | Credits under sections 901 and 960 cut by 10%, plus 5% for each further 3 months after the 90 days |
| Wilful failures | Criminal penalties under sections 7203, 7206 and 7207 may apply |
Separate $10,000 penalties apply under section 6046 for Schedule O reporting of acquisitions and dispositions.
Example only: Emeka, a green card holder in Texas, owns 60% of a Port Harcourt engineering company and is a director. He is a Category 4 filer (control), and because he alone owns more than 50% the company is a CFC, making him a Category 5 filer too. He has not filed for 2024 or 2025. That is two missed annual periods: a possible $20,000 in initial penalties before any IRS notice, which is why people in his position talk to a cross-border accountant about the IRS relief routes before the IRS writes first.
What you need from Nigeria
- The company's audited accounts or statement of accounts for the year, in English. CAMA s.402 exempts some small companies from audit, so a management statement may be all there is.
- The share register and CAC status report showing who owns what, including relatives, since constructive ownership counts.
- Details of dealings between you and the company: salary, loans, dividends, purchases.
- Nigerian tax paid by the company, if any. PwC's summary (May 2026) notes small companies pay 0% company income tax, which matters for any credit.
Ask the Lagos accountant to prepare the accounts early; a US return due in April needs Nigerian numbers well before then.
Common mistakes
- Assuming a company that never paid a dividend needs no US form. Form 5471 turns on ownership and roles, not distributions.
- Ignoring relatives' shares. Stock owned by family members can be attributed to you when testing the 10% and 50% thresholds.
- Filing for yourself but not for your spouse, when both hold shares and both are US persons.
- Treating a share transfer or a new allotment as a Nigerian-only event. Crossing 10% either way can make you a Category 3 filer for that year.
- Leaving the Nigerian accounts until the US deadline is days away.
Changes from the 2025 tax law
The December 2025 instructions already reflect parts of Public Law 119-21, including a rule from section 70352 limiting how a foreign corporation's tax year can differ from its majority US shareholder's for years beginning after 30 November 2025. Read the latest revision for the year you are filing. For what the CFC status means for tax, see is my Nigerian company a CFC and GILTI for small Nigerian companies.

Questions people ask
Do I need to file Form 5471 for my Nigerian company?

$10,000 per foreign corporation per year, plus $10,000 for each 30 days after an IRS notice, up to $50,000 more, and a reduction in foreign tax credits.
When is Form 5471 due?
With your income tax return, including extensions. It is attached to the return, not filed separately.
